Description

[Detailed Description of the Invention] The present invention relates to a seat cushion mounting structure for an automobile.

Conventionally, an automobile seat cushion has been installed in a structure in which a locking portion provided at the bottom of the seat cushion is inserted into a hook attached to a floor panel. For example, Utility Model Application Publication No. 57-53935 is an example, and although this structure is effective in preventing the hook attached to the floor panel from coming off,
Difficulty in aligning the locking part when inserting it into the hook, vibrations of the vehicle body causing a metallic friction noise between the locking part and the hook, and the locking part coming off the hook due to a car collision, etc. There were problems such as the possibility that the seat cushion might jump up.

In view of this point, the present invention provides a synthetic resin block member having an engaging vertical groove and a vertical wall portion and a stopper portion formed on the upper part of the engaging vertical groove, which is attached to the vehicle floor, and the aforementioned engaging member provided on this block member. It is an object of the present invention to provide a seat cushion mounting structure for an automobile that solves the above-mentioned problems by fitting and locking an engaging protrusion attached to the lower part of the seat cushion into the vertical groove.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings.

The drawing shows a seat cushion mounting structure for an automobile according to the present invention.
A vertical wall portion 2 that is substantially flush with the inner surface of one side of the engagement vertical groove 1 and extends upward; and a stopper portion 3 that extends upwardly from the upper end of the vertical wall portion 2 by bending it upward. A synthetic resin block member 5 having a groove formed therein is attached to an attachment hole 7 provided in a floor panel 6 of the vehicle body.

The cross-sectional shape of the longitudinal engagement groove 1 is an oblong shape, and the stopper portion 3 extends above the engagement longitudinal groove 1 by bending the upper end of the vertical wall portion 2 . A flange plate 8 is provided laterally protruding from the outer periphery of the upper end of the block member 5, and a vertical wall portion 2 and the upper end of the vertical wall portion 2 are bent at the upper part of the flange plate 8 at an intermediate portion of the engagement vertical groove 1. A stopper portion 3 formed as shown in FIG. And the flange plate 8
At the bottom of the floor panel 6, there are several leg plates 10a, 10 at positions that fit around the periphery of the mounting hole 7 provided in the floor panel 6.
b, 10c, 10d are provided in a protruding manner, and the block member 5 is fitted and locked into the mounting hole 7 by the leg plates 10a. A locking claw 11 is formed on the outer surface of each leg plate 10a, and the locking claw 11 and the flange plate 8 are installed on the floor panel 6 at the periphery of the mounting hole 7 and on the floor panel 6. It is secured by sandwiching the floor mat 12. In addition, each leg plate 10a is preferably provided so as to project slightly outwardly so as to be elastically pressed in the direction of the circumferential edge of the attachment hole 7.

An engaging protrusion 13 that is fitted into and locked in the engaging longitudinal groove 1 of the block member 5 is attached to the lower part of the cushion frame 16 of the seat cushion 15. The engagement protrusion 13 is a substantially U-shaped member, and both ends of the engagement protrusion 13 are fitted into through holes 17 provided in a recess 16a formed in the cushion frame 16.
Both ends are bent, and the bent portions 13a, 13b are welded to the inner surface of the cushion frame 16.

Next, the installation of the seat cushion 15 with the engaging protrusion 13 attached to the lower part of the vehicle body floor 4 will be described.

First, the locking portion 13 of the engaging protrusion 13 is placed on the collar plate 8 of the synthetic resin block member 5 attached to the vehicle floor 4.
c (shown by the chain line in FIG. 2), and the locking portion 13
When c is moved toward the vertical wall portion 2, the locking portion 13c
descends within the engagement vertical groove 1. In this way, the seat cushion 15 is attached to the vehicle body floor 4. When removing the seat cushion 15 from the vehicle floor 4, the locking portion 13c may be moved in the opposite direction. Note that the lower end surface 3a of the stopper portion 3 is connected to the engagement protrusion 1.
The locking portion 13c of No. 3 can easily enter the engaging vertical groove 1,
It is slanted in a shape that makes it difficult to slip out unexpectedly.

As explained above, the seat cushion mounting structure of the vehicle according to the present invention includes an engaging vertical groove whose upper surface is open and a vertical engaging groove which extends upward and is substantially flush with the inner surface of one side of the engaging vertical groove. A synthetic resin block member having a wall portion and a stopper portion whose upper end is bent and extended above the engagement longitudinal groove is attached, and the lower portion of the seat cushion is fitted into the engagement longitudinal groove of the block member. The seat cushion is designed to fit and lock the engagement protrusion installed on the seat cushion, so even if the attachment position of the engagement protrusion and the block member is slightly misaligned, the seat cushion can be securely attached to the vehicle floor without causing play. Since it has a stopper part and a vertical wall part, it is easy to align the mounting position. Furthermore, since the block member is made of synthetic resin material, metal friction noise does not occur. Furthermore, even in the event of a collision, the engagement protrusion is reliably locked by the stopper portion, so the seat cushion does not jump up. In addition, the seat cushion can also be removed.
